This study conducted among Dutch children age 10-12, focuses on friendships
with Dutch and other nationality contemporaries. The study was designed to
test among older children several hypotheses derived from intergroup theor
y. Particular attention is paid to the self-affective consequences of group
evaluations. It is found that children make a clear distinction between fr
iendships with own and other nationalities. In addition, stronger national
identification is related to less social distance towards Dutch contemporar
ies and to more social distance towards other nationalities. Furthermore, o
wn group ratings in particular had a self-enhancing effect among children s
coring high on national identification; children indicating little social d
istance towards the own group reported more positive momentary self-feeling
s after the group evaluations. It is concluded that different psychological
mechanisms determine the own group and other group aspects of national dif
ferentiation.
